SPECIFICATION forming part of Letters Patent No. 412,433, dated October 8, 1889.

' Application filed May 15, 1888. Serial No. 273,991. (No model.)

To all whom it may concern.-

Be it known that I, HARRISON H. TAYLOR, acitizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Machines for Turning the Ends of Pieces of Metal; and I declare the following to' be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. My invention has for its object an improved machine for turning the ends of pieces of metal; and it consists of the combinations of devices and appliances herewith illustrated v in the drawings and more fully described in the following specification and hereinafter set forth in the claims.

In the drawings, Figure 1 is a plan view of.

a machine embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a longitudinal vertical section along the linen; m, Fig. 1. Fig. 4: is a'horizontal section along yy, Fig.

'1, showing parts in plan, and Fig. 5 is'an end View of the shaft carrying the cutter. Fig. 6 is a separate view of one of thapieces of metal, showing the-blank in full lines-and the ends turned by the herein-described machine in dotted lines.

I carry out my invention as follows:

A represents any suitable support.

B is a rotatable shaft journaled upon the support in any suitable manner, as in journal boxes 1) b, engaged thereupon. Upon said shaft is located a stop-wheel B, a ratchetwheel B and a jaw B notched upon one of its faces, as at 19 for the reception of the pieces of metal U, which are to be turned at their ends.

' C represents also a rotatable shaft, journaled upon the support in any suitable manner, as in journal-boxes c c. This shaft C is located slightly at an angle to the line of the shaft B and carries a jaw C at its inner end, constructed with notches at 0 upon its inner face,-co rresponding to the notches b upon the adjacent jaw 13 These notches may have any required shape to receive the pieces of metalto be turned, the combined notches b 0 respectively serving to receive a piece of metal. The two jaws C B are simulta neously rotatable when one or more pieces of metal are engaged in said notches, although the jaw B may be rotated independently. It will be seen that owing to the shaft C being located at an angle to the shaft B the two jaws will have a binding pressure, the one inner edge against theothel' adjacent to the cutter, thereby gripping the metal pieces to be turned with great force, holding them firmly in'place, while at the same time the said jaws opposite the cutter will be separated and opened apart, so that the pieces of metal may be readily fed into the notches, any suitable number of notches being provided. This construction permits the ready insertion and removal of the pieces, as well as serving to hold them firmly atjust the required point.

The shaft B is operated in the following manner: D is a driving shaft suitably journaled upon the support, as at d d. D is a drivingpulley. E is a pawl constructed to engage the ratchet-wheel B and to this end may be supported upon a crank-arm E. E" is a connecting=rod engaged with said arm and extending rearwardly, and preferably has a bent or hooked extremity e, adapted to rest upon the driving-shaft when in normal position. The connecting-rod may have any suit able tightening or adjusting device 6. The driving-shaft is provided with a crank-arm D provided with a crank-pin d. It is obvious that as the shaft revolves said pin will come into contact with the connecting-rod above it, lift it from the driving-shaft, and as the rotation is continued the rod will be forced rearward, the pawl at the opposite end thereby forcing over in a corresponding direction the ratchet-wheel l3 and shaft B, and conse quently the jaw B By making the teeth or recesses of the ratchet-wheel correspond in distance apart to the distance between the notches in said jaw, and the recesses or notches of both the jaw and ratchet wheel to correspond to the throw of the connecting-rod, it will be seen that said throw will then bring the successive pieces of metal in the jaws adjacent to the cutter, a piece of metalbeing thus brought to the cutter at each revolution of the driving-shaft D. A spring IE will draw the ratchet back for a new hold when the pin d has let go the connecting-rod. A stop E may be located to limit the retraction of the pawl. The stop-wheel B may be locked in any desired manneras, for instance, by means of a sliding dog or bolt F, arranged to engage suitable orifices in the stop-wheel or recesses 12 thereupon. F is a jointed rod engaged with the looking-bolt, the said rod being jointed at f, and also having a jointed engagement with the bolt, as shown at f. The rear end of the said rod is engaged with any suitable support, as upon an arm F secured upon the support A. The crank-arm D is provided also with an additional pin (1 and the rod with an inclined flange or shoulder f As. the arm D is rotated the pin d will engage said shoulder f flex the jointed rod upward at the point f, thereby withdrawing the 1ocking-dog from the stop-wheel, permittin g its rotation, and allowing the ratchetwheel and jaw B to rotate, the stop-wheel when dogged, however, serving to hold the rotating shaft in firm position, so that the work will be held securely to the knife or cutter. A spring F will retract the rod F, throwing the dog into engagement with the stop-wheel, and so long as the rod F is held in a straight position the dog will be engaged and hold the stop-wheel.

The looking or stop wheel, the ratchetwheel, and the adjacent jaws may all be con-.

structed with an equal number equidistant from each other.

G is a rotatable spindle carrying the cutter g upon the head of the spindle G. This spindle is journaled upon the support A, as shown at g g and is provided with a driving-pulley G This shaft is made reciprocatory as well as rotatable, and may be provided with an adjusting-screw 9 whereby its reciprocation may be controlled. The spindle is forced forward to the work by means of a cam D upon the driving-shaft D. It may be retracted by any suitable means, as by a weight H, suspended to a bell-crank I, pivoted on the support and engaged with the spindle.

The cutter may be provided with a setscrew 9 to adjust the same as desired.

The various parts are so related that the spindle will be retracted; then the bolt withdrawn from the stop-wheel; then the ratchetwheel actuated and held in position by the retraction of the locking-bolt to engage the stop-wheel, the cutter also returning to its work.

To limit the in ertion of the pieces of metal in the jaws C 13 I have shown an intermediate disk J the jaws O B being recessed to receive it. This disk J may be centered upon a spindle J, engaged in the tubular journal 0. As so constructed and arranged the intermediate disk may be readily changed of notches,

to conform to various lengths of pieces of metal to be turned. This may be accombe forced too firmly together adjacent to the cutter. A bar K may be also located at the end of the journal B, which may or may not be a spring-bar, said bars K K serving to hold their adjacent journals firmly to the work, yet permitting the jaws to yield laterally if occasion requires.

What I claim is- 1. In a machine for turning the ends of pieces of metal, the combination, with the rotatable jaws 0 B constructed to receive the pieces of metal between their adjacent faces, of a disk located between the jaws to limit the engagement of said pieces therewith-sub stantially as set forth.
